fix(powerdns): use 'launch=' instead of 'launch+=' for gsqlite3 backend

PowerDNS 5.x requires a parent 'launch=' directive before any
incremental 'launch+=' can be used. Since the install script
comments out the default 'launch=' in pdns.conf, the 'launch+='
in gsqlite3.conf fails with:
  Fatal error: Incremental setting 'launch' without a parent

Use 'launch=gsqlite3' (non-incremental) since gsqlite3 is the
only backend needed.
